20 Current Two-Phase ASTM Approval Process 20

21 Overview and Potential Impact of NJFCP Vision Develop an experimental and analytical capability to facilitate OEM s evaluation of fuel physical and chemical properties on engine operability and to streamline ASTM fuels approval process. IMPACT Early fuel screening (Tier 2.5), targeted Tier 3 and 4 tests, and increased OEM confidence 21

22 Overview and Potential Impact of NJFCP Expand & Employ Gained Knowledge Base No Redesign/Reengineer Fuel Development Pathway Acceptable Combustor Operability? Yes Scope of Tier 3/4 Testing Determined by NJFCP Results NJFCP: Detailed Fuel Testing & Combustion Modeling at an extended range of conditions Tier NJFCP learnings, tests, or screening: Testing and/or Modeling Route Determine initial estimate of maximum percent blend of new fuel with Jet-A Expensive Certification Tests, which the NJFCP strives to reduce. 22

23 NJFCP Executive Summary (testing) Lean Blowout (key certification criteria): Fuels with distillation, viscosity, and DCN (in particular) extremes observed to exhibit deleterious performance characteristics. For most rigs, Lean Blowout (LBO) was found to correlate with DCN (new result relative to prior studies) OEMs have identified this as a major NJFCP benefit Ignition (key certification criteria): Initial fuel screening at relevant conditions suggests that high initial distillation temperatures and properties associated with poor spray atomization lead to deleterious performance. Initial NJFCP results are consistent with prior experimental studies 23

24 NJFCP Executive Summary (modeling) Chemical Kinetics: Progress achieved connecting fundamental shock tube results to test rig Lean Blowout results. Additional in situ hydrocarbon species measurements have enabled greater model fidelities. Chemistry model approach for jet fuels validated and documented Computational Fluid Dynamics (CFD): Teams are iterating towards predicting Lean Blowout trends for selected NJFCP fuels. CFD combustion model developed into OEM common format routine (CFR) for alternative jet fuel evaluation in OEM hardware. 24
